When lifting the torso up and reduced blade athlete seek to bend the back, trunk extension is only granted to the horizontal position, in any case not higher. It should be emphasized that should draw the hips, pelvis is suspended; exercise is carried out only with the weights, and these weights can only serve bar. Exercise is good develops the lowest part of the back extensors, of course, when the above conditions.

So, the whole muscle mass back presents more than two dozen muscles, forming the largest muscle area of the human body, this muscle ensemble produces is good development of the back muscles and the unique effect of massiveness muscularity simultaneously. The main functions of the back muscles include lowering and retraction down arms and straightening the spine. Distinguishing feature of the spinal cord in addition to a large array surface is a significant thickness or depth of the formed multilayer arrangement of muscles.

The two main features - motor function and a significant depth of topographic localization of muscle and determine the features of the array back muscle development.

All spinal array for convenience can be divided vertically into three parts - upper, middle and lower distinguishing outer, middle and inner zones of these parts. Thus, we can distinguish between: the upper back - from the base of the neck and around to the bottom of the blades, the middle part - from the lower edges of the blades to the lower edge of the costal arches, the lower edge of costal arches and to the sacrum is the lower back.
